NPE during FIND_MBRS when using shared transport ------------------------------------------------ Key: JGRP-1862 URL: https://issues.jboss.org/browse/JGRP-1862 Project: JGroups Issue Type: Bug Security Level: Public(Everyone can see) Affects Versions: 3.5 Reporter: Paul Ferraro Assignee: Bela Ban Priority: Blocker Fix For: 3.5 The following code within org.jgroups.protocols.TP.sendToSingleMember(...) throws an NPE if the transport is shared: {code} Responses responses=(Responses)up(new Event(Event.FIND_MBRS, Arrays.asList(dest))); try { for(PingData data : responses) { if(data.getAddress() != null && data.getAddress().equals(dest)) { if((physical_dest=data.getPhysicalAddr()) != null) { sendUnicast(physical_dest, buf, offset, length); return; } } } } finally { responses.done(); } {code} This is because up(Event) always returns null when using a shared transport. The same issue affects org.jgroups.protocols.TP.fetchPhysicalAddrs(...): {code} if(!missing.isEmpty()) { Responses rsps=(Responses)up(new Event(Event.FIND_MBRS, missing)); rsps.done(); } {code}
